The OV5647 device +node should contain one 'port' child node with an 'endpoint' subnode.
The remote-endpoint property in endpoint nodes should be mandatory, shouldn't it? Otherwise the sensor isn't connected to anything and hardly useful as such. The list of optional endpoint properties is a long one and it should be documented here which ones are recognised, either as optional or mandatory.
